Twig_String_Loader hick-up with variable names using underscores

[zebba]

I've set-up a small test-case that demonstrates a hick-up the Twig_String_Loader currently has: it doesn't process properties that user underscores in their name, using {{ foo.acme_string }} to access $acme_string will fail with

Twig_Error_Runtime: Method "acme_string"
for object "Tests\Foo" does not exist
in "{{ foo.int }}, {{ foo.acme_string }}"

Although as per doc-comment on the Loader\String the loader should only be used for testing purposes this should work anyway. Else it is not really suitable for testing.

Well, actually, the Twig_Loader_Array is more suitable for testing purpose. The Twig_Loader_String does not allow extending another template (well, unless you put the content of the parent template in the {% extends %} tag, which makes it useless). The actual use case for the string loader is template_from_string().

but your own issue has nothing to do with the string loader. foo.acme_string does not work for other loaders either (it has nothing to do with the template loading btw). It looks like you expect the behavior of https://github.com/fabpot/Twig/pull/1299, but this Pr is not merged

You should never use the Twig_Loader_String loader. I made it clear in d12f7af. Use String_Loader_Array instead.
